I am probably the oldest lurker, born in 1933 (a vintage year). Enlisted in the USAF after high school graduation and stayed for 21 years as an Avionics Technician. Next 6 years working on a BS and Masters in Zoology.....retired for good about 1985 and have been piddling around ever since.
Many PS/2s including 3 model 80s, 1 model 65, 1 model 60, 2 - 77s, a 40 I am working on right now......and my newest prize possession is a P70 I just got and haven't even turned on yet. (Also have an AT, an XT, a PS/1 Consultant and a PC300PL which is my main machine.....for now!)
